Ni-doped Ni3S2 nanoflake intertexture grown on graphene oxide as sheet-like anode for high-performance lithium-ion batteries

Ni3S2 has become a promising anode material for lithium-ion batteries (LIBs) due to its favorable electrochemical conversion reaction, high theoretical specific capacity, and low cost. In this work, a nanoflake-assembled Ni-doped Ni3S2 sheet-like nanocomposite (Ni3S2–Ni–NF) was constructed using graphene oxide as the structure-directing agent by a simple two-step solvothermal reaction. The design of nanoflake subunit, sheet-like morphology, and...
